About Our Environmental Program

The Tri-County Regional Planning Commission is designated by the state as the region's areawide water quality management planning agency under the Clean Water Act. Tri-County strives to protect and enhance our environment's built and natural resources, including ground and surface water, water and sewer infrastructure, and the quality of our air. Our environmental programming focuses on planning for the future and ensuring our region has access to unpolluted surface water, sustainable groundwater resources, healthy and safe drinking water, and an environmentally sustainable transportation system. 

​

Tri-County staff manages several technical groups, initiatives, and organizations that work to achieve these goals. We support and guide the region’s vision for sustainability by providing technical assistance to local governments, educating the public and local leaders, hosting forums for peer-to-peer knowledge sharing, and connecting people and places to resources that promote the shared stewardship of our built and natural resources.
